They are very cool and came as an option with some of the SVTs. That price is about right from Ford, and the price has gone up dramatically in the last 3 months (since I've been looking for them). Keep with the want to buy ad and check on Ebay. Every once in a while they pop up there and sell for around $550 for the set. Be sure when you do find a set that all the bulbs are intact. The other thing is that they are not plug and play unless you purchase the adapters which will run a little more money. Good luck in your search. I'm sure you'll be happy with them if you buy them.
